Abstract

Field-induced successive transitions were observed in magnetoresistance in the quasi-one-dimensional organic conductor, HMTSF-TCNQ, hexamethylene- tetraselena-fulvalene-tetracyanoquinodimethane. The magnetoresistance exhibits kink transitions accompanying hysteresis at pressures around 1 GPa, but neither at p=0 nor at 2 GPa. At p=0 and below 30 K, this material undergoes charge density wave (CDW) state, which is suppressed around 1 GPa, where successive transitions are observed. Since these behavior is only observed at the boundary in pressure between insulator and metal, and the nature of the insulating state is CDW at p=0, it is strongly suggested that the successive transitions observed in magnetoresistance might be associated with CDW, accordingly a field-induced CDW by the one-dimensionalization by strong magnetic field ranging from 10 to 30 T. The behaviors are compared with previously claimed FICDW and the established FISDW (field-induced-spin-density-wave).
